Toshiba L350 - 107 runs fine on battery reboots on poweradapter.... problem

Hello , My name is Jan Elze

My Toshiba has a stange problem when running on the battery there's no problem , but when the adapter is connected, the laptop reboots and keeps rebooting .
but when I boot up in windows safe mode it runs fine even when the adapter is connected .
also when I boot up Lindows CD there's no problem .

The CPU is not overheating
the adapter is replaced and checked
I changed the Harddrive
I even changed the OS from Windows 7 64bit to windows 7 32 bit version .
also the windows vista gives the same problems ...

also in the windows safe mode with network the laptop gives no problems
only when windows is running normal then when I plug in the adapter the laptop shutdown and reboots

Is there someone who knows this problem ?? I dont know any solutions anymore ...Please Help !!

 

Not sure how to help, but one thing worth checking is to make sure your fans/vents are clean of any accumulated dust [use compressed air with short bursts]. Accumulated dust could cause thermal shutdowns [your laptop turning off from overheating]. Checking your temperatures can also verify whether to cooling system is functioning properly [can use the free programs called HWinfo or HWmonitor].

Your laptop may not have the problem while on battery because when your laptop is plugged into an outlet, it would switch power plans from battery[power saving] to outlet[maximum performance]; thus if the cooling system was compromised, it would leading to overheating and a forced shutdown.


Good luck and keep us updated with any results.

 

Thnx for the reply , but The airvents are totaly clean , that was the first thing I checked .. the CPU and the chipset does'nt exeed the 50 C

I even put all the functions in the power manager the same in Battery and net-power ..? I start to think that it must be a failure on the MB ....
maybe a capacitor...or something ????

 

Now I even tried to disable one Core in the bios and disabled the multi core feauture of the CPU in the bios .
I tried to update the Bios but I have the latest version so no can do ..... I,me realy running out off options ..

 

Oke , I know now what the problem is , there is a capacitor broken and must be replaced .

 

Hey; Thanks for the update!!
I'll also have to remember this diagnosis for future troubleshooting.

 

can you replace that capacitor or total mother board now its work on adapter mode because my laptop also same problem so please reply

 

I replased the capacitor ,
I replased with 6 x 150 uF
in the satalite 305-107 laptop its the NEC/TOKIN 0E907 (900uF/2.5V)
but you need to look inside under the proccessor on the backside off the mother-board
becuase some Toshiba's used Nek/Tokin 0E128 (1200 uF / 2,5V )
to try if its the capacitor you can diconect the proccesor in windows-safe-mode and the restart in normal windows .
if windows is started then you can plug in the adapter . if the laptop keeps running it is most likely the capacitor ..

Greetings

 

I have the same problem with Toshiba L355-S7812. Do you think the same capacitor will work for me and where could I get one.

 

you need to look inside the laptop because there are several different capacitors used in the laptops .
and for replaceable parts you can buy them on ebay , or you can replace them with other capacitors and make sure you get the
micro-farad correct, the voltage is not so important , if you keep the capacitors over the 2,5 volt ..
